"We've investigated that with the gentleman in question," Pruitt said. Udall also asked Pruitt about a tweet issued by EPA's official account last month mocking Democratic senators for failing to block the confirmation of Andrew Wheeler, a former coal lobbyist now working as EPA's No. 2 official. The tweet potentially violated federal anti-propaganda rules.

Pruitt says his staff shouldn't have issued the tweet.

President Donald Trump's embattled Environmental Protection Agency head is distancing himself from controversies at his agency by blaming subordinates for ethical missteps.

Scott Pruitt is testifying before a Senate Appropriations subcommittee, and he's being pressed by the top Democrat about his unusual security demands.

New Mexico's Tom Udall is asking Pruitt whether he directed his security detail to use lights and sirens to speed through Washington traffic, even when there wasn't an emergency.

Pruitt isn't answering directly. He says there are policies in place and he's confident his staff has followed them.

The senator has asked again whether Pruitt gave such an order. Pruitt says, "I don't recall that happening."

Udall is citing an email written by EPA's security chief saying Pruitt "encourages the use" of emergency lights.
